Not much is known about the mysterious Apprentice of Master Xenahort, only that he is skilled with a Keyblade and adept at Magic.
Cold, callous, calculating, ruthless. All dark words to describe such a dark being, one who lusts for the powers of darkness.
His Keyblade also has a similar centre to Way to the Dawn and Soul Eater, with a blue, demonic eye just above the handle.
Not revealed at the moment.
